The MADCSM0001 has a 50-ohm matched input, consumes low DC power and incorporates an on-chip switch that determines CDMA and AMPS mode select. The designer can tailor the linearity and gain performance of the MADCSM0001 according to the system needs. The MADCSM0001 is ideally suited for wireless applications where low noise, low current and high linearity are important features . The MADCSM0001 is fabricated using M/A-’s 0.5-micron low noise E/D Ga As MESFET process. The process features full passivation for increased performance and reliability.
